ALS Data and Status

The ASTATUS register is required for automatic gain control

(AGC). It provides an ALS saturation and ALS gain status

associated to each set of ALS data. Reading the ASTATUS

Reading these 13 bytes consecutively (0x94 - 0xA0) ensures that

the data is concurrent. All ALS data are stored as 16-bit values.

If flicker detection is enabled, ALS channel five is used for the

flicker detection function and ADATA5 will read 0. The ASTATUS

and ALS data registers are read only.

Bit Description

ASAT_STATUS

ALS Saturation Status. Indicates if the latched data

is affected by analog or digital saturation.

6:4

Reserved

3:0

AGAIN_STATUS

ALS Gain Status. Indicates the ALS gain applied for

the ALS data latched to this ASTATUS read. The ALS

gain from this status read is required to calculate ALS

results if AGC is enabled.
